Question

The electric potential at a point in an electric field is defined as:

विकल्प

• The work done by an external agent in bringing a unit positive test charge slowly from infinity to that point, against the electrostatic force

• The total charge enclosed within a sphere of radius equal to the distance of that point from the charge

• The work done in moving a unit negative charge from that point to infinity

• The force experienced by a unit positive test charge placed at that point

Answer 1

Electric potential is defined as the work done by an external agent in bringing a unit positive test charge slowly from infinity to a point in an electric field, against the electrostatic force. It measures the work needed per unit positive charge, not the force (which defines the electric field).
